V-BLAST detectors: Performance investigation in correlated condition and time analysis

Multiple antenna systems provide an enormous increase in spectral efficiency compared with single antenna systems. Various transceiver and receiver techniques have been developed over the years to detect the symbols with as far as possible, small error from the mixed symbols. In this paper, an attempt has been made to make comparative study on time consumption of each technique and all the techniques have been simulated in correlation conditions involving two practical correlation matrices and the SNR loss and BER deteriorations have been pointed out.
